Only you can tell by observation and time. No crystal ball here, especially as we have no idea how the tree's been taken care of otherwise. Why aren't there pebbles in the saucer keeping the pot out of the water?

I dont usualy even use the stupid things. I dont worry about humidity cause ihave so many other trees around i only did it so i didnt have run off on to the the trees on the bottom shelf. Oops.
